The belt receiving portion 317 may be mounted on the upper surface of the base frame 310 and form a suction hole 318 communicating with the communication groove 313.

The belt seating part 317 can prevent the absorption belt 350 from moving unnecessarily or being separated from the belt seating part 317 because the absorption belt 350 is seated and a part of the absorption belt 350 can be covered.

The belt seating part 317 includes a vertical part 319 which surrounds the suction hole 318 and is vertically protruded to contact with the suction belt 350 on which the suction hole 351 is formed.

The vertical portion 319 is formed so that the suction hole 351 contacts the belt seat portion 317 when the suction belt 350 is continuously moved by the driving portion 330 and the suction hole 351 And can be prevented from being closed.

That is, the suction belt 350 is in contact with the vertical portion 319, so that even when the suction belt 350 is moved by the driving unit 330, the suction holes 351 and the suction holes 318 It can always be communicated.
